A root perforation and treatment.
According to Lemon (1992) the internal matrix concept of repairing perforations has distinct advantages over the surgical method. The procedure is more time-efficient when compared with other methods. The technique requires direct access and visualization of the perforation site in order to place the repair material. It is therefore restricted to perforations in the furcation area, and the straight portions of the root canal.
